Please I want the solution in compact form.

3. A foundry smelts steel, aluminum, and cast iron scraps to produce two types of metal ingots, and II, with specific limits on the aluminum, graphite and silicon contents. Aluminum and silicon briquettes may be used in the smelting process to meet the desired specifications. Table 3 and Table 4 set the specifications of the problem: Input item Available tons/day Steel scrap Aluminum scrap Cast iron scrap Aluminum briquette Silicon briquette Table 3.
